So I am about halfway through my gt40p head installation, and I am missing one nylon pushrod guide insert. This is my daily driver, so it has to be up and running by Tuesday to go to work after Labor Day. There's no way I will be able to get one, and nobody carries these locally.

Should I be concerned if I just ignore it?

You're gonna have a mess if you try to run that engine w/o that guide insert in there. Do not run that engine for even a minute.

#1. Your pushrods are probably not hardened, and they'll make contact with that guideplate.

You take a piece of steel,.....apply about 300 pounds of force to push it against another piece of steel, and then rub them violently against each other thousands of times per minute.

How long do you spose it'll take before the one starts to wear on the other? Did you say minutes?

But worse than that.

#2. The extra slop that will now be there in between the space that the pushrod rides in w/o that insert will allow the rocker arm to move side to side. So much so, I'd be worried that the rocker arm could come off the valve stem, and depress the retainer. Press on the retainer, valve stays put, locks come off, valve drops into the engine,...............................Boom!
 
What, I get no love for saving another of my favorite engines?:shrug:
I guess, if it makes you feel better, but I still would have run it. I've seen cars drive weeks with loose/broken/misaligned rocker arms, bent/worn pushrods, guides that were so worn they no longer served a purpose and all sorts of nightmarish things they shouldn't....and they kept right on ticking. I don't believe him doing so would be the overdramatize equivalent to pulling the pin on a grenade That you outlined, but to each their own.

Personally, I wouldn't think twice about using it minimally, with some easy driving for a day or two till the part came in, but if it's going to make his butthole pucker doing so, he should probably wait.

You know how it goes,...what you get/got away with, and what running examples of carnage you can cite does not make it worth running the risk of engine damage for the sake of a missing .99 part.

I've swapped out carburetors 30 times on an engine.

I only burnt one of them to the ground as a result.

Dang! A double like from the two hardest likes to get on Stangnet! I'm on fire tonight.:flame:
I use them sparingly. That way, when you see that I "liked" something that you said,....You know that I liked it.

I Consider it like an antibiotic. Dr's try not to over-prescribe them so that a virus cannot become immune to it's benefit.
